MACHINE FOR CLEANING PAPER, 800.

SPECIFICATION forming part of Letters Patent No. 253,992, dated February 21, 1882.

Application filed August 31, 1880. (No model.)

To all whom it may concem:

Be it known that I, FRANCIS J. EMMEaIcH of the city of New York, in the county and State of New York, have invented certain new andusefulImprovementsin MachinesforOleaning Paper and other Fabrics, of which the following is a specification.

Although my machine may be used in brushing sheets of paper or fabric to free them from powder, dust, or any other substance which may be readily removed by brushing, it is particularly desirable for brushing paper which has been previously printed in sizing and bronzed, for the purpose of brushing off the surplus bronze-powder which is commonly used for the purpose.

An important object of my invention is to provide a machine which will do this work in a rapid and effective manner, without the liability of marrin g or soiling the sheets of paper with dust, dirt, orpowder after theyhave passed the brushes or brushing devices by which the work is performed. 7

To this end the invention consists in the combination, with two brushes, of chains or carriers and attached gripers, which are intended to grasp the sheets at their front edges and draw them between the brushes, which brush the two sides of the sheets at once. The gripers extend from one chain to the other, so as to grasp the sheets along their entire edges, and one of the brushes may be moved away from the other as the gripers approach them, to allow the gripers to pass between them, after which they are again adjusted to bear upon the sheet on opposite sides.

The invention also consists in the combination, with a brush or brushes and the chains or carriers andgripers, of channels, grooves, or guides, which receive the ends of the gripers and hold them closed upon the sheet of paper to draw it forward, and-cams which first close the gripers on the sheet and direct them into said channels or guides. The chains or carriers have an intermittent motion and stop to take the sheet; and in order to insure their stoppingat their proper position I employ stops, which are obtruded in the way of the gripers to prevent the momentum of the chains or carriers from carrying them beyond theproper stopping-place, and which are then moved to permit the chains or carriers to move forward.

The inventlon also consists in a novel construction of rotary brushes, which I may employ in my machine.

The invention also consists in the combination, with the chains or carriers and gripers, of a rising and fallingfeed-table, which is raised to permit the gripers to pass under it, and is then moved down orlowered to permit the sheet of paper to'be fed into the open gripers as they pause in front of the edge of the feed-table.

The invention also consists in minor details of construction and combinations of parts, to be hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of my improved machine, a portion of one of its cams being broken away to show the parts behind it. Fig. 2represents a side view of one of the brushes of the machine. Fig. 3 represents an end View of a modified form of brush upon a larger scale. Fig. 4 represents an end view of the machine, the feedtable and appurtenances being removed; and Fig. 5 represents a portion of a chain or carrier, gripers attached thereto, the adjacent portion of the frame, and the mechanism for" closing the gripers on the paper and holding them closed, all upon a larger scale.

Similar letters of reference designate corresponding parts in allthe figures.

A designates the side frames ofthe machine, which may be of any suitable form, and are united by suitable cross-rails or stretchers.

B designates the main driving-shaft, mounted in suitable bearings and adapted to be rotated by any suitable means.

In the upper part of the frames Aare inserted two rotary brushes or cleaning-rollers, H W, arranged one above another, and rotary motion is imparted to them by belts B running over pulleys I? on the driving-shaft B. The two brushes should rotate in opposite directions, so that their adjacent faces will move in the same direction,and toeffect this the belt which imparts motion to the upper brush, W, may be crossed, as seen-in Fig.1, while the belt which imparts motion to the lower brush, H, may be straight. r 1

In Figs. 2 and 3 I have represented two forms of brush or cleaning-roller, either of which may be employed.

The brush or roller represented in Fig. 2 comprises a central shaft and fabric disks, a, secured on the shaft between two flanges, d, which are fitted to and tightly secured on the shaft. The faces of both flanges d are parallel with each other and oblique to the shaft, forming an angle of about sixty degrees (60) with the shaft. Consequently the several fabric disks 0 are all set obliquely to the shalt at a corresponding angle, and when thus arranged will come in contact with all parts of and thoroughly clean the paper passed between them.

The roller or brush H represented in Fig. 3 comprises a longitudinal shaft or core, a, of wood or other material, fitted therein, and hair or bristles b are inserted into the said core, so that they will stand radially or tangentially thereto. The hair or bristles b may be surrounded by a covering or jacket, 0, of fur, velvet, or other material adapted to form a soft and effective surface.

Near each side of the machine is an endless chain or carrier, T, and to these chains or carriers are secured gripers S, which extend from one to the other, and are adapted to grasp or gripe a sheet of paper along its entire front edge. The chains or carriers T are mounted on chain-wheels on the shaft E and on corresponding pulleys on the shaft J.

G designates a shaft which is rotated by means of a belt, 0, from a pulley, (F, on the driving-shaft B, and D designates a corresponding and parallel shaft which receives rotary motion from a pinion, n, on the shaft 0, engaging with a wheel, 9, on the shaft D.

Upon the shaft D is loosely mounted a wheel, Y, which engages with a pinion, 2, on the shaft E, and to said wheel is fitted a conical clutchpiece, f, which is operated through a clutchjoint, m, by a cam, i, on the wheel 9. So long as the cam i holds the clutch-piece f in engagement with the wheel Y the shaft E is rotated positively, and the chains or carriers T, with their attached gripers S, are made to travel; but as soon as the let-off of the cam comes into action the clutch-piece f is released from its seat in the wheel Y and the chains or carriers and their attached gripers stop.

In order to enable the gripers S to pass between the rollers or brushes H and W, it is necessary to separate them, and in this example of my invention the lower brush or roller, H, fitslin bearings in plates or boxes h, adapted to move vertically upon the side of the frame A, and these plates or boxes are connected by rods r with arms G, which are fulcrumed upon a rock-shaft, I. Upon the rockshaft I is a third arm or lever, G, which is acted upon by a cam, F, on the shaft D, and by this means the roller H is moved down to permit the gripers to pass, and is immediately returned to its normal or operative position. v

M designates the feed-table, which is hinged at its rear edge at V, and is adapted to swing upon its hinges to give it a rising-and-falling movement, the rising movement being necessary to enable the gripers S to pass under it, and the falling movement being likewise necessary to enable the sheet of paper to be fed from the feed-table into the open gripers S,

which stand open in froutof it, as shown clearly in Fig. 1.

The requisite rising-and-falling movement is given to a table, M, by means of a slide-bar, L, movably secured to the frame A of the machine, and a cam, K, 011 the shaft D, which acts upon said slide-bar to raise it, while the weight of the table returns it after being raised.

The gripers S, when not otherwise actuated, are held open by springs, and after a sheet has been fed into them it is necessary to close them and keep them closed while they draw the sheet through between the brushes H W.

011 the inner sides of the frames A are slideways or guides U U, in which the chains or carriers T run, and as soon as the gripers en ter these they are held closed; but it'is necessary to close them on the sheet before they commence their forward movement. To this end I employ sliding rods B, one at each side of the machine, which are secured to the inner sides of the frame A, so that they may move vertically. The heads or upper ends of the sliding rods It project inward into the path of the gripers, as seen in Fig. 5, and when the said rods are drawn down these heads strike upon the gripers and close them, and then hold them closed until they have moved forward sufficiently to enter the grooves or guides U U, after which they are held closed.

To the lower ends of the sliding rods R are connected curved armsQ,exteudingfrom arockshaft P, and said rods R are always held in a raised position by a weight, X, when not drawn down.

On the rock-shaft P is an arm or lever, O, which bears upon a cam, N, on the shaft D, as seen in Fig. 1 in dotted outline, and the rods R are drawn down at proper intervals to close the gripers by the aforesaid cam.

When the machine is running quite rapidly and is suddenly stopped the momentum of the chains or carriers might carry the scrapers too far beyond the front edge of the feed-table M, and to prevent this I provide lips or ears I on the bars or rods R, which obtrude themselves in front of the gripers and form stops for an resting the forward movement of the gripers. When the rods or bars R are drawn down to close the gripers the lips or cars lare withdrawn from in front of the gripers, and the lat ter are free to move ahead.

The sheet of paper or fabric taken by the gripers S is drawn between the rapidly-rotatin g cleaning rollers or brushes, the adjacent snr faces of which move in the opposite direction to that in which the sheet is moving, and there by the sheet is thoroughly cleaned of all sur plus bronze-powder or other substance, and as the sheet is only held at the front edge there IIO is no danger of its becoming smutted, dusty, or dirty. When the gripers S reach the ends of the guides or grooves they open and the sheets drop onto a receiving board or table placed immediately below the carrying or upper portions of the chains or carriers and between them.

What I-claim as my invention, and desire to secure by Letters Patent, is-
